Project summaryDeaths from cancer worldwide will continue to rise, with an estimated 12 million deaths in 2030. Prostate cancer, after lung cancer, is the second cause of cancer death in men worldwide. Some advanced prostate cancers have well known symptoms. However non-cancerous diseases of the prostate, such as benign prostatic hyperplasia (BPH) cause same symptoms. On the other hand, at very early stages, prostate cancer has no symptoms, the tumor dimension is quite small and it is extremely difficult to detect it. At the later stages, treatment or surgery has very low efficiency. To find cancer in people who do not have symptoms of that disease is extremely important. If prostate cancer is detected at an early stage it can be successfully cured by different methods. Consequently, it is possible to save lives.
Different methods, such as measurement of the amount of prostate specific antigen in the blood, digital rectal examination, trans-rectal ultrasound diagnosis are used for prostate cancer diagnosis. Unfortunately these methods are not able to detect cancer at early stage of it’s development.
Magnetic resonance imaging and positron emission tomography made advances in prostate cancer diagnosis. However, these methods require extremely expensive and complicated technique and could not be used widely in clinics. Besides, high magnetic field and radiofrequency irradiation, X-rays, radioactive substances used in these methods also can post some risk. Unfortunately, there is no low cost and easy method so far which could give reliable diagnose of prostate cancer at early stages, when the dimensions of newly developed cancer tissue are of millimeter or sub-millimeter size.
In this project, we propose to create an advanced, simple, cost effective and reliable system for early diagnosis of prostate cancer. This system could be placed at any clinic for prostate cancer diagnosis. This system will not require special skills or experience from the personnel. The methodology is based on established fact that near infrared light may pass through biological tissues. Special software will be developed for analysis of prostate infra-red images. The diagnosis system would allow distinguishing differences between cancerous and noncancerous tissues and identify the location of the cancer. Charge-coupled device (CCD) camera connected to the computer will be used as infrared images detector.
It is difficult to overemphasize economic, social and other impact of our device - it will help to save lives.
Doctor of biological science Besarion B. Partsvania will be the Project manager. B. Partsvania is highly qualified scientist. His specialization is biophysics. He was manager-principal investigator in numerous scientific projects, particularly in projects awarded by ISTC, GNSF etc. During last two years Partsavnia participated in 9 international scientific forums. His total number of publications is 80. Publications of B. Partsvania together with G. Petriashvili and other team members concerns to the issue of proposed project are:
